The stock results show that the Formula Maximus Special Edition performs well; and the overclocked results show that it can reach clock speeds fairly close to the maximum of other X38 and P35 boards. The dual PCIe 2.0 16x slots mean that you will not run out of PCIe bandwidth for high end CrossFire setups; frankly, video cards are no where near saturating even a PCIe 1.0 8x link in dual card configurations, so the Maximus leaves you with plenty of headroom. The SATA performance of the board was excellent.
